HARVESTER-BINDER.

SPECIFICATION forming of Letters Patent No. 485,956, dated November 8,1892.

Application filed January 8, 1891.

To aZZ whom it may concern..-

Be it known that I, JOHN LUND, of the town of Woodstock,in the countyofOxford,in the Province of Ontario, Canada, have invented certain new anduseful Improvements in Harvester-Binders, of which the following is aspecification.

The object of the invention is to provide simple and effective trippingand discharging mechanism and means for more effectually compressing thesheaf and regulating the tension of the binder-twine while the knot isbeing tied; and it consists in the peculiar construction, arrangement,and combinations of parts hereinafter more particularly described andthen definitely claimed.

Figure 1 is a perspective view showing the position of the mechanismprevious to the binding of the sheaf. Fig. 2 is a perspective view justprior to the discharge of the bound sheaf. Fig. 3 is a perspectivedetail showing the knotter-operating and needle rock-shaft gearinglocked. Fig. 4 is a detail of the bindertwine tension-regulator. Fig. 5is a detail of the idler-spring sprocket-wheel and attachments. Fig. 6is a detail of the clutching mechanism and sprocket wheels unlockedimmediately after the clutch-tri ppin g arm has been thrown out fromengagment with the clutch. Fig. 7 is a side view in detail showing theconnection of the pitman-rod and sprocketwheelA. Fig. 8 is a front viewin detail showing the connection of the pitman-rod to the sprocket-wheelA. Fig. 9 is a front view of the cam formed on sprocket-wheel A. Fig. 10is a perspective skeleton view showing the relative positions of theneedle, compressor-trip, needle-shaft, and crank-arm when the knot isready for stripping. Fig. 11 is a detail showing a vertical section ofthe upper part of the pitman.

In Fig. 1, A is the sprocket-wheel, which moves in the direction of thearrow and opcrates the knotter-opcratin g shaft B. O O are thedischarge-arms in the position they assume after the bound sheaf hasbeen discharged and before the compressor-trip D has released the clutchtrip-arm E, Figs. 3 and 6, and thrown into gear the knotter-operatingmechanism and operated the needle rock-shaft F. The needle-shaft F hasbearings within the sleeve 6, supported by frame-pieces 7 and Serial No.377,142. (No model.)

8, the end being journaled atfon the framepiece g, and 10 is the hub ofthe needle, to which the end of compressor-trip D and tension-rod 5 arepivoted. G is the needle in the position it assumes after the sheaf hasbeen discharged and before the compresson trip D has been tripped. H isthe compressorarm, pivoted at h to the breast-plate I, the upper end ibeing preferably curved, as shown in the drawings, with its extremityhookshaped, and held in position while the sheaf is being packed againstit by the packers J J by the pressure of the eccentric semicircleK(carried by the knotter cam-disk N, mounted on shaft B) against the bentend '6 of the compressor-arm H. The com pressor-trip D is pivotallyattached at one end atj to the hub 10 of the needle G and in this Viewis shown in its intermediate position, while the sheaf is being packedand previous to tripping, whereas in Fig. 2, which clearly shows itspivotal position with the hub of the needle, it is in its raisedposition, as hereinafter explained. it is the sprocket-chain, whichdrives the knotter-operating mechanism. (Vida, also, Fig. 3.) At Xisshown a lug on the hub 10, against which the tech of the compressor-tripD rests prior to the packing of the sheaf, or when the sheaf is fi rstbeing packed. When a sufiicient weight of sheaf has been packed on topof the compressor-trip D, the toe part b presses on the lug X and causesthe hub 10 and the needle-shaft F to rock. lhe rocking of theneedle-shaft releases the lock-arm E (shown in Figs. 5 and 6) when theneedle and knotting mechanism is thrown into operation,and as the needlemoves around into the position shown in Fig. 2 the toe b and the lug Xon the hub move away from each other, and the toe Z) or incline formedbeneath the compressor-trip D runs upon the wheel 0 and is raised upagainst the bottom of the sheaf while the k not is being tied.

In Fig. 2 the compressor-trip D, having been slightly depressed by thepacked sheaf, has moved the needle rock-shaft F and disengaged theclutch-trip arm E from the stop 1, formed on the clutch L, pivoted tothe sprocket-wheel M (more particularly referred to under Fig. 3) thussetting in motion the knotteroperating mechanism. In this view, Fig. 2,the sprocket-wheel A and the kno'tter camdisk Non shaft 13, whichcarries the eccentric semicircle K, has made about a half-revolution ormore in the direction of the arrowhead and the knot has been tied andthe cord cut, and the sheaf which is in the actof being discharged bythe discharge-arms O, which have completed more than a half-revolutionin the direction of the arrow-head, has thrown the compressor-arm E intothe position shown in the drawings, the arm H being free to swing on itspivot it, because its upper endt'has ceased to engage with the eccentricsemicircle K, which has been moved out of its way. In this view it willbe noticed that the compressor-trip D, being pivotally attached at oneend to the hub of the needle G, moves longitudinally and upwardly as theneedle embraces the sheaf, the toe b of the slanting shoe cZ, formedunder it, running upon the grooved wheel 0, which is journaled on ashaft 0, running in brackets O, attaehed to the frame and raising thecompressor-trip D against the bottom of the sheaf, While the needle Gand the compressor-arm I-I embrace or compress the sheaf, holding ittightly until the knot has been tied and the twine cut and the needlecommences to recede to the position it occupies during the packing ofthe new sheaf.

In Fig. 3 c is the sleeve supported on the frame of the machine bystandard 11 and frame-piece 12, Fig. 2, which supports the theknotter-operating shaft B, and 7c is the sprocket-chain which is kepttaut by the spring-idler sprocket-wheel P. In this view the clutchtrip-arm E is engaged with the stop Z, formed on the clutch L, which ispivoted to the sprocket-wheel M by pivot n. The end of the clutch whichcarries the stop Z moves on the guide-lugo,which passes through the slot19, formed in the clutch. Q is the packer-shaft, which rotatescontinuously in the direction indicated by arrow-head when the machineis in operation, carrying with it the contact-lugs g, formed thereon.The clutch trip-arm E is rigidly attached to or forms part of theneedle-shaft crank-arm R, attached to the needle rock-shaft F. S is thepitman-rod pivotally attached at r to the nee-.

dle-shaft crank-arm R, and so arranged, as hereinafter explained, as tobe capable of yielding slightly at the proper moment by reason of themode of connection of its upper end to the crank-pin s, and thusshortening the length of the pitman S at the moment that the clutchtrip-arm E is disengaged from the stop Z when tripped by the motion ofthe compressor-trip D. When the clutch trip-arm E has become disengagedfrom the stop Z, the heavy or weighted end tof the pivoted clutch Ldrops, throwing the contact-roller m on the clutch into the path of arotating driving-lug g on the packer-shaft Q, the parts assuming theposition indicated in Fig. 6. WVhen the driving-lug 9 comes in contactwith the contact-roller m, the sprocket-wheel M is carried round,driving the sprocket-wheel A and actuating the knotter operating shaftB, which sets in motion the knotting mechanism, as well as the needlerock-shaft F, which derives its rocking motion by the raising andlowering of the needle-shaft crank-arm R by means of the pitman-rod S,which is attached at its upper end to the crank-pin s, rotating with thesprocket-wheel A. The dischargearms 0 0 continue to move round with theshaft, discharging the bound sheaf, until they have completed onerevolution, when the clutch-trip arm E again comes round and engageswith the stop Z, throwing the contactrollerm away from the driving-lugg,when the motion of the sprocket-wheelM is arrested and the needle, aswell as the knotter-operating mechanism, ceases to move until thecompressor-trlp D, weighted down with the newlypacked sheaf, againdisengages the clutch trip-arm E from the stop Z,and the needle,knotting mechanism, and the discharge-arms C O are again put in motion.The spring-idler sprocket P keeps the chain taut, as shown in Fig. 3, byreason of the coil spring it, which passes round a hub through which thepackershaft passes, and is secured at its upper end to the binder-frame,and bearing at its lower end against a lug 12, formed on the hangingbracket to, to the lower part of which the idler sprocket-wheel P isjournaled. (See Fig. 5.) The upper end of the bracket w is pivotallyattached to the packer-shaft Q, the lower end being thrown out by thepressure of the spring on the lug 'u, as before mentioned. At 21 (seeFig. 10) is shown the knotter-bill, and at 22 the knot ready forstripping.

Figs. 7, 8, 9, and 10 illustrate the constructionof the adjustableconnection of the pitman S with the crank-pin s on the sprocketwheel A.S is the pitman-rod, the upper end of which is screwed into thepitman-box T. The end of the pitman projects into the interior of thepitman-box, and around it is a coiled extension-spring bearing on oneend on an adjustingnut y and on the other against the movable box 2,which by the action of the spring a: bears against the bottom of thecrank-pin s. As the pitman S has in moving the needle-shaft crank-arm Rup and down both a pulling and a pushing action to insure rigidity ofconnection at the proper time, a cam U is formed on the shoulder of thecrank pin s and rigidly attached thereto and is notched at V. This camengages with a lug W, formed on the pitman-box T, which is hung on thecrank-pin s, the periphery of the cam moving over the lug WV during therotation of the sprocket-wheel A and taking the push of the pitman S offthe coil-springa; within the pitman-box T. When the clutch trip-arn1 Ehas completed its rotation and become engaged with the top Z and whenthe trip action again takes place, the stop W is in thepositionindicated in Fig. 9, so that when the clutch trip-arm E, whichis attached to the pitman, is thrown up the pitman-rod yields by reasonof the lug W on pitman-box T entering the notch V in the cam U, so as toallow of the spring x being compressed, and the box a, which bearsagainst the crankpin 8, has a play between the points 1 and 2, (shown inFig. 8,) thus permitting the shortening of the pitman-rod S at theproper moment.

Fig. 4 illustrates the tensionregulator, which is also shown in positionin Fig. 3. 3 is a bracket attached to the frame and formed of a T-shapedpiece of metal, the parts forming the head of the T being bent at rightangles and having two eyes therein through which, as Well as through aslot 4, formed in the tensionrod 5, the binder-twine is threaded. Oneend of this tension-rod is pivotally attached to the compressor-trip Don the hub of the needle and the other rests on a guide formed by a holein the bracket. When the needle Gis at rest, the cord passes through theeyes and slot in a straight line, allowing it to pass through withoutfriction and permitting a free delivery of cord to the binder while thesheaf is being packed into it. When the needle moves to bind the sheafthe tension-rod 5 is drawn over by the motion of the hub of the needle Gand pulls on the string and puts a tension thereon at the proper timewhen the knot is being made.

When the machine is in operation, the packer-shaft Q is continuouslyrotating, and the packers J J, affixed thereto, pack the newly-formingsheaf on top of the compressortrip D. Then a sufficient weight has beenimposed on the compressor-trip D, it becomes depressed, causing theneedle rock-shaft F to move, and disengages the clutch trip-arm E fromengagement with the stop Z. The knotteroperating mechanism anddischarge-arms, as well as the needle rock-shaft, then commence tooperate. A tension is put on the bindertwine, the knot tied, the twineis cut, and the bound sheaf is discharged, as already described, andwhen the clutch trip-arm E becomes again depressed, after the dischargeof the sheaf, it engages again with the stop Z, throwing thecontact-roller m away from the driving-lug g, and the discharge-arms,knotter-operating mechanism, and needle cease to move, assuming andretaining the normal position shown in Fig. 1 until the compressortrip Dagain becomes depressed, disengaging the clutch triparm E from the stopZ, when the operation of tying and dischargingasheaf is again repeated.

From an inspection of Fig. 10 it will readily be seen that the knot iscomplete up to the point of being ready for stripping before the needlehas commenced to move back, and

consequently the knot is tied while the compressor is moving with alongitudinal and upward course, as the crank-pin has just arrived at thedead-center. This arrangement has the following advantages: Bycontinuing the compression of the sheaf by the compressor-trip till theknot is completed an economy of cord is effected and a better-shapedsheaf is produced. If the compressor-trip had not a longitudinal andupward motion as the knot is being tied, all the compression of thesheaf at that time would be from the moving needle, which would tend toproduce a flattened sheaf, which would necessarily be of greatercircumference than the round sheaf produced when the compression is fromtwo sides at once, and in consequence of this a saving of cord iseffected by the twofold compression while the knot is being tied.Further, as the sheaf is compressed by the compressor-trip after thecord has been laid round it and grasped in the cord-holder theknotter-bill can take with ease the necessary cord to form a knotwithout strain on the knotter.

What I claim as my invention is 1. In a harvester-binder, thecombination, with the needle rock-shaft actuated as specified, of theneedle, a knottenoperating disk, an eccentric semicircle on theknotter-operating disk, a compressor adapted to be operated by saideccentric semicircle, and a compressor-trip adapted to have alongitudinal and upward motion as the knot is being tied, substantiallyas specified.

In a harvester-binder, the combination of the needle G, mounted on ahub 10, having a lug X, a pivoted compressor D, pivotally attached toand carried by the hub of the needle G, the shoe d, having an inclinedbottom and toe b, engaging lug X, the needle rockshaft F, actuated asspecified, and the grooved wheel 0, substantially as described.

3. The combination of the sprocket-wheels A and M, hanging bracket to,lug c, sprocketwheel P, coil-spring a, mounted on a hub around thepacker-shaft Q and having one end bearing against part of the frame andthe other against said bracket, and the chain 70, around wheels A and Pand under wheel M, substantially as specified.

4. The combination of the pitman-rod S, pitman-box T, adjustable springm, inclosed in said box, movable box 2, bearing against the crank-pin s,the notched cam U, and lug W, substantially as described and shown.
